Title: Digital television receiver, video data transmission circuit and video data reception circuit
Inventor: WATANABE HIDEKI
IPC: H04N5/44
Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To enable serial data transmission of video data at a low transmission speed of 20 Mbps or less. SOLUTION: A video data output means 10 outputs a video image clock and video image data. If a serial data transmission speed is lower than prescribed, a first select means 14 outputs a video clock multiplied by a clock multiplier circuit 13 to a serial data transmission means 15 by a selection signal of a selection means 11. Also, the video clock is outputted as a reproduction clock from a reproduction clock means 12 by the selection signal of the means 11. The means 15 transmits video data, a reproduction clock, the selection signal, and a synchronous clock to a serial data receiving means 16. The means 16 outputs the video data, the regenerated clock, the selection signal and the synchronous clock from the received serial data.  A second select means 17 outputs the regenerated clock by the selection signal, and a video data receiving means 18 receives the video data synchronously with the regenerated clock. In this way, serial data transmission with a low transmission speed can be enabled.
